Post Subject: HELP on a Custom 3 Way Horn with Beyma TPL150Posted by vakman on: 12/25/2019
Hi All,
This is my 1st ever post, but extremely disappointed I never came across this site before
Here is my current setup, for which I'm desperately seeking some help from fellow members- Cabinet - Layered Birch Ply with curved sides
- Woofers [93.67dB]- 2 x 10" - Acoustic Elegance TD10M (2 woofers per cabinet)
- Midrange [110dB]- 2" Compression Driver - Radian 651 BePB-8 (Beryllium)
- Horn - KH-53 A (53cm) - Jabo Horns Germany
- Tweeter [99dB]- Beyma TPL150
- MiniDSP for the Woofers and ported using 2 x 3" flared ports on the backside of each cabinet.
- Passive crossover for Midrange and Tweeter at this stage using ALL Mundorf Supreme Silver/Gold In Oil. Inductors are ALL Mundorf Copper
- Attenuator Fostex R100T2 for the Horn (MidRange) used to bring down the 100dB Horn running the Radian 651 BePB-8
Amplification- Custom 300B monoblocks for the Mids and Highs
- Krell FPB300Cx for the Woofers
Current Crossover Points- Woofers 20Hz to 860Hz
- Midrange 775Hz - 4250 Hz
- Tweeter 4000Hz +Hz
Current Crossover- Horn lower crossover point is 775Hz using 18uF caps and 2.2mH Coil (second order)
- Horn/tweeter crossover point is 4,250Hz using 4.7uf caps plus 0.3mH coils (first order)
The sound: We'll it's not bad, but lacks the delicacy and intimacy of my old Fountek Neo 5i Ribbon tweeter in my previous 2-way setup. The sound can best be described as impactive & full range, but lacking that suck me into the music (toe tapping factor).
Was thinking about replacing the Beyma TPL150 with the RaaL Lazy Ribbon, but unsure at this point and didn't really want to commit a large sum of money unless I was sure.
Any guidance would be much appreciated.
